Serial Interface Clock. Synchronizes serial data transfers. Data is input on the rising edge and output on the
falling edge.
Serial Data OUT. Serial data is read from this line when using a 3-wire serial protocol such as the
Motorola Serial Peripheral Interface.
Serial Data IN or OUT. This line is bidirectional programmable and interfaces directly to the Intel Standard Serial
Interface using a 2-wire serial protocol.
Chip Select Input. Used to select the HI7190 for a serial data transfer cycle. This line can be tied to DGND.
An Active Low Interrupt indicating that a new data word is available for reading.
Digital Supply Ground.
Negative Analog Power Supply (-5V).
External Reference Input. Should be negative referenced to V
External Reference Input. Should be positive referenced to V
Common Mode Input. Should be set to halfway between AV
Analog Input LO. Negative input of the PGIA.
Analog Input HI. Positive input of the PGIA. The V
the condition of an external transducer. This current source is controlled via the Control Register.
Positive Analog Power Supply (+5V).
Analog Supply Ground.
Positive Digital Supply (+5V).
Used to connect a crystal source between OSC
Oscillator Clock Input for the device. A crystal connected between OSC
or an external oscillator can drive OSC
Active Low Reset Pin. Used to initialize the HI7190 registers, filter and state machines.
Active Low Sync Input. Used to control the synchronization of a number of HI7190s. A logic ‘0’ initializes the converter.
Mode Pin. Used to select between Synchronous Self Clocking (Mode = 1) or Synchronous External Clocking
(Mode = 0) for the Serial Port.
